Check the listing for details. Three (3) Coleman (same as part #216-5091) - Leather Pump Cups. Condition: New. Listed at 12.50 USD. 3 leather pump cups. These are the common size that fit the vast majority of Coleman products. The cup diameter is approximately 7/8" (also referred to as the 21mm size). These are made by me from high quality vegetable tanned leather -- vegetable tanned leather is safe for use with the metal in your stove/lantern. (Non-vegetable tanning processes have chrome alum/chromium salts in the leather which corrode metal over time). These leather cups are a perfect fit in your Coleman lantern or stove. These work in Coleman lanterns and camp stoves that are white gas / Coleman camp gas / naphtha / kerosene / liquid fueled. I can send them pre-soaked in neatsfoot oil so you can use them immediately or I can send them dry for longer term storage so they won't attract dust. **Just let me know how you want them (by default I will send them pre-soaked). I will email installation instructions (with photos) of how to install the leather pump cups with purchase. Leather cups can be installed in just a few minutes with just common everyday household tools/items. Get rid of the neoprene cups! Upgrade to leather. At checkout, please indicate if you want them dry in the note to seller box - otherwise I will send them pre-soaked (the default).
